TECHNICAL FIELD

This invention relates to tetrahydroquinoline derivatives that act as modulators of the P2X7 receptor. The present invention also relates to processes for the preparation of the compounds, pharmaceutical compositions containing the compounds, and to their use in the treatment of a wide range of diseases, syndromes, and disorders, which are associated with P2X7 receptor activity such as diseases of the autoimmune and inflammatory system, diseases of the nervous and neuro-immune system, diseases involved with neuroinflammation of the Central Nervous System (CNS) or diseases of the cardiovascular, metabolic, gastrointestinal and urogenital systems.

BACKGROUND ART

The P2X7 receptors (P2RX7) belong to the family of P2X ionotropic receptors that are activated by extracellular nucleotides, in particular adenosine triphosphate (ATP). P2X7 receptor is distinguished from other P2X family members by the high concentrations (mM range) of ATP required to activate it and by its ability to form a large pore upon prolonged or repeated stimulation (NPL 1 to NPL 3: North, R. A., Physiol. Rev. 2002, 82(4), 1013-67; Surprenant, A., Rassendren, F. et al., Science 1996, 272(5262), 735-8; Virginio, C., MacKenzie, A. et al., J. Physiol., 1999, 519, 335-46). The P2X7 receptor is a ligand-gated ion channel and is present on a variety of cell types, largely those known to be involved in the inflammatory and/or immune process, specifically, macrophages and monocytes in the periphery and predominantly in glial cells (microglia and astrocytes) of the CNS. (NPL 4 to NPL 6: Duan and Neary, Glia 2006, 54, 738-746; Skaper et al, FASEB J 2009, 24, 337-345; Surprenant and North, Annu. Rev. Physiol. 2009, 71, 333-359).

P2X7 receptor is located on many cell types, especially ones known to be involved in inflammatory and immune processes. Activation of the P2X7 receptor by extracellular nucleotides, in particular adenosine triphosphate, leads to the release of proinflammatory cytokines IL-1 beta and IL-18 (NPL 7: Muller, et al., Am. J. Respir. Cell Mol. Biol. 2011, 44, 456-464), giant cell formation (macrophages/microglial cells), degranulation (mast cells) and L-selectin shedding (lymphocytes) (NPL 8 to NPL 9: Ferrari et al., J. Immunol. 2006, 176, 3877-3883; Surprenant and North, Annu. Rev. Physiol. 2009, 71, 333-359). P2X7 receptors are also located on antigen-presenting cells (keratinocytes, salivary acinar cells (parotid cells)), hepatocytes, erythrocytes, erythroleukaemic cells, monocytes, fibroblasts, bone marrow cells, neurones, and renal mesangial cells.

The importance of P2X7 in the nervous system arises primarily from experiments using P2X7 knockout mice. These mice demonstrate the role of P2X7 in the development and maintenance of pain, as these mice are protected from the development of both adjuvant-induced inflammatory pain and partial nerve ligationinduced neuropathic pain (NPL 10: Chessell et al., Pain 2005, 114, 386-396). In addition, P2X7 knockout mice also exhibit an anti-depressant phenotype based on reduced immobility in forced swim and tail suspension tests (NPL 11: Basso et al., Behav. Brain Res. 2009, 198, 83-90). Moreover, the P2X7 pathway is linked to the release of the proinflammatory cytokine, IL-1 beta, which has been linked to precipitation of mood disorders in humans (NPL 12 to NPL 13: Dantzer, Immunol. Allergy Clin. North Am. 2009, 29, 247-264; Capuron and Miller, Pharmacol. Ther. 2011, 130, 226-238). In addition, in murine models of Alzheimer's disease, P2X7 was upregulated around amyloid plaques indicating a role of this target in such pathology as well (NPL 14: Parvathenani et al., J. Biol. Chem. 2003, 278, 13309-13317).

There is therapeutic rationale for the use of P2X7 ion channel blockers in the treatment of a variety of disease states. These include but are not limited to diseases associated with the central nervous system such as stroke or injury and diseases associated with neuro-degeneration and neuroinflammation such as Alzheimer's disease, Huntington's disease, epilepsy, Amyotrophic lateral sclerosis, acute spinal cord injury additionally to meningitis, sleep disorders, mood and anxiety disorders as well as chronic and neuropathic and inflammatory pain. Furthermore, peripheral inflammatory disorders and autoimmune diseases including but not limited to rheumatoid arthritis, osteoarthritis, psoriasis, allergic dermatitis, asthma, chronic obstructive pulmonary disease, airways hyper-responsiveness, septic shock, bronchitis, glomerulonephritis, irritable bowel disease, skin injury, lung emphysema, Limb girdle dystrophy type 2B, fibrosis, Syndrome of synovitis Acne Pustulosis, atherosclerosis, burn injury, spinal cord injury, Hyperostosis Osteitis, Crohn's disease, ulcerative colitis, growth and metastases of malignant cells, myoblastic leukaemia, diabetes, trauma, meningitis, osteoporosis, burn injury, ischemic heart disease, and varicose veins and trauma, are all examples where the involvement of P2X7 channels has been implicated. In addition, a recent report suggests a link between P2X7 receptor and chronic, inflammatory and neuropathic pain (NPL 15: Chessell, I. P., Hatcher, J. P. et al., Pain, 2005, 114(3), 386-96). Overall, these findings indicate a role for the P2X7 receptor in the process of neuronal synaptic transmission and therefore a potential role for P2X7 antagonists as novel therapeutic tools to treat neuropathic pain.

In view of the above observations, there is significant requirement for P2X7 antagonists that can be efficiently used in the treatment of a wide range of diseases, syndromes, and disorders, which are associated with P2X7 receptor activity such as diseases of the autoimmune and inflammatory system, diseases of the nervous and neuro-immune system, diseases involved with neuroinflammation of the CNS or diseases of the cardiovascular, metabolic, gastrointestinal and urogenital systems.

Several reviews on small molecule inhibitors of P2X7 which have been published are: NPL 16: Guile, S. D., et al., J. Med. Chem, 2009, 52, 3123-3141; and NPL 17: Gunosewoyo, H. and Kassiou, M., Exp Opin, 2010, 20, 625-646.

International patent application PTL 1: WO 2013/108227 purportedly describes aza-bicyclic pyridine derivatives as a P2X7 receptor antagonist. The chemical structures are dihydrofuropyridine derivatives and dihydropyranopyridine derivatives, which are quite different from tetrahydroquinoline derivatives of the present invention. They neither disclose nor suggest teterhydroquinoline derivatives.

Recently, PTL 2: WO 2016/039983 and PTL3: WO 2016/019228 also disclose aza-bicyclic compounds with P2X7 receptor antagonistic activities. Each chemical structure is triazolopyrazine derivative and indolizine derivative, respectively, which is quite different from a tetrahydroquinoline derivative of the present invention.

SUMMARY OF INVENTION Technical Problem

There is a need in the art for P2X7 antagonists that can be used to treat a disease, syndrome, or condition in a mammal including human, wherein the disease, syndrome, or condition is affected by the modulation of P2X7 receptors, such as diseases of the autoimmune and inflammatory system; diseases of the nervous and neuro-immune system; diseases involved with, and without, neuroinflammation of the CNS; diseases of the cardiovascular, metabolic, gastrointestinal and urogenital systems; skeletal disorders, diseases involving the secretory function of exocrine glands and glaucoma, Glomerulonephritis, Chaga's Disease, chlamydia, neuroblastoma, Tuberculosis, Polycystic Kidney Disease, cancer, and acne.

It is an objective of the invention to provide new P2X7 receptor antagonists that are good drug candidates. P2X7 antagonists should be well absorbed from the GI tract and should be metabolically stable and possess favorable pharmacokinetic properties. They should be non-toxic. Furthermore, the ideal drug candidate would exist in a physical form that is stable, non-hygroscopic and easily formulated. In particular, it has been desired that compounds would have to bind potently to the P2X7 receptor and show functional activity as antagonists. Also it has been desired that compounds would have favorable pharmacokinetic properties.

Solution to Problem

With respect to other compounds disclosed in the art, the compounds of the present invention may show less toxicity, good absorption and distribution, good solubility, less plasma protein binding, less drug-drug interaction, good metabolic stability. The present invention provides novel compounds which have excellent P2X7 antagonistic activities as well as excellent pharmacokinetic properties.

In addition, the tetrahydroquinoline derivatives of the present invention show an excellent selectivity for the P2X7 channel as compared with other P2X families, especially P2X1 channel. Involvement of P2X1 against auto regulation in kidney has been reported in P2X1 antagonist (NF 279) (Purinergic Signalling (2012) 8:375-417). Thus, selective P2X7 compounds of the present invention lead to improvements in the side-effect profile.

Sci, 66, 1-19, 1977, such as acid addition salts formed with inorganic acids e.g. hydrochloric, hydrobromic, sulfuric, nitric or phosphoric acid; and organic acids e.g. succinic, maleic, formic, acetic, trifluoroacetic, propionic, fumaric, citric, tartaric, benzoic, p-toluenesulfonic, methanesulfonic or naphthalenesulfonic acid. Certain of the compounds of the present invention may form acid addition salts with one or more equivalents of the acid. The present invention includes within its scope all possible stoichiometric and non-stoichiometric forms. In addition, certain compounds containing an acidic function such as a carboxy can be isolated in the form of their inorganic salt in which the counter ion can be selected from sodium, potassium, lithium, calcium, magnesium and the like, as well as from organic bases.

Also within the scope of the invention are so-called “prodrugs” of the compounds of the present invention. Thus, certain derivatives of compounds of the present invention which may have little or no pharmacological activity themselves, when administered into or onto the body, can be converted into compounds of the present invention having the desired activity, for example, by hydrolytic cleavage. Such derivatives are referred to as “prodrugs”. Further information on the use of prodrugs may be found in Pro-drugs as Novel Delivery Systems, Vol. 14, ACS Symposium Series (T Higuchi and V Stella) and Bioreversible Carriers in Drug Design, Pergamon Press, 1987 (ed. E B Roche, American Pharmaceutical Association).

Prodrugs in accordance with the invention, for example, can be produced by replacing appropriate functionalities present in the compounds of the present invention with certain moieties known to those skilled in the art as ‘pro-moieties’ as described, for example, in Design of Prodrugs by H Bundgaard (Elsevier, 1985). Some examples of prodrugs in accordance with the invention include:

(i) where the compound of the present invention contains an alcohol functionality (—OH), compounds wherein the hydroxy group is replaced with a moiety convertible in vivo into the hydroxy group. Said moiety convertible in vivo into the hydroxy group means a moiety transformable in vivo into a hydroxyl group by e.g. hydrolysis and/or by an enzyme, e.g. an esterase. Examples of said moiety include, but are not limited to, ester and ether groups which may be hydrolyzed easily in vivo. Preferred are the moieties replaced the hydrogen of hydroxy group with acyloxyalkyl, 1-(alkoxycarbonyloxy)alkyl, phthalidyl and acyloxyalkyloxycarbonyl such as pivaloyloxymethyloxycarbonyl; and

(ii) where the compound of the present invention contains an amino group, an amide derivative prepared by reacting with a suitable acid halide or a suitable acid anhydride is exemplified as a prodrug. A particularly preferred amide derivative as a prodrug is —NHCO(CH₂)₂OCH₃, —NHCOCH(NH₂)CH₃ or the like.

Further examples of replacement groups in accordance with the foregoing examples and examples of other prodrug types may be found in the aforementioned references.

The compounds of the present invention, salts thereof and prodrugs thereof may be prepared in crystalline or non-crystalline form and, if crystalline, may optionally be hydrated or solvated. This invention includes within its scope stoichiometric hydrates or solvates as well as compounds containing variable amounts of water and/or solvent.

Salts and solvates having non-pharmaceutically acceptable counter-ions or associated solvents are within the scope of the present invention, for example, for use as intermediates in the preparation of other compounds of the present invention and their pharmaceutically acceptable salts.

Additionally, the compounds of the present invention may be administered as prodrugs. As used herein, a “prodrug” of a compound of the present invention is a functional derivative of the compound which, upon administration to a patient, eventually liberates the compound of the present invention in vivo. Administration of a compound of the present invention as a prodrug may enable the skilled artisan to do one or more of the followings: (a) modify the onset of action of the compound in vivo; (b) modify the duration of action of the compound in vivo; (c) modify the transportation or distribution of the compound in vivo; (d) modify the solubility of the compound in vivo; and (e) overcome a side effect or other difficulty encountered with the compound. Typical functional derivatives used to prepare prodrugs include modifications of the compound that are chemically or enzymatically cleaved in vivo. Such modifications, which include the preparation of phosphates, amides, esters, thioesters, carbonates, and carbamates, are well known to those skilled in the art.

In certain of the compounds of the present invention, there may be some chiral carbon atoms. In such cases, compounds of the present invention exist as stereoisomers. The invention extends to all optical isomers such as stereoisomeric forms of the compounds of the present invention including enantiomers, diastereoisomers and mixtures thereof, such as racemates. The different stereoisomeric forms may be separated or resolved one from the other by conventional methods or any given isomer may be obtained by conventional stereoselective or asymmetric syntheses.

Certain of the compounds herein can exist in various tautomeric forms and it is to be understood that the invention encompasses all such tautomeric forms.

The invention also includes isotopically-labeled compounds, which are identical to those described herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, iodine, and chlorine, such as ³H, ¹¹C, ¹⁴C, ¹⁸F, ¹²³I and ¹²⁵I. Compounds of the invention that contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of the present invention. Isotopically-labeled compounds of the present invention, for example those into which radioactive isotopes such as ³H, ¹⁴C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i.e., ³H, and carbon-14, i.e., ¹⁴C, isotopes are particularly preferred for their ease of preparation and detectability. ¹¹C and ¹⁸F isotopes are particularly useful in PET (positron emission tomography), and ¹²⁵I isotopes are particularly useful in SPECT (single photon emission computerized tomography), all useful in brain imaging. Further, substitution with heavier isotopes such as deuterium, i.e., ²H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically labeled compounds of the invention can be generally prepared by carrying out the procedures disclosed in the Schemes and/or in the Examples/Intermediates below, then substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.

A pharmaceutical composition of the invention, which may be prepared by admixture, suitably at ambient temperature and atmospheric pressure, is usually adapted for oral, parenteral or rectal administration and, as such, may be in the form of tablets, capsules, oral liquid preparations, powders, granules, lozenges, reconstitutable powders, injectable or infusible solutions or suspensions or suppositories. Orally administered compositions are generally preferred. Tablets and capsules for oral administration may be in unit dose form, and may contain conventional excipients, such as binding agents (e.g. pregelatinised maize starch, polyvinylpyrrolidone or hydroxypropyl methylcellulose); fillers (e.g. lactose, microcrystalline cellulose or calcium hydrogen phosphate); tableting lubricants (e.g. magnesium stearate, talc or silica); disintegrants (e.g. potato starch or sodium starch glycolate); and acceptable wetting agents (e.g. sodium lauryl sulphate). The tablets may be coated according to methods well known in normal pharmaceutical practice.

Oral liquid preparations may be in the form of, for example, aqueous or oily suspension, solutions, emulsions, syrups or elixirs, or may be in the form of a dry product for reconstitution with water or other suitable vehicle before use. Such liquid preparations may contain conventional additives such as suspending agents (e.g. sorbitol syrup, cellulose derivatives or hydrogenated edible fats), emulsifying agents (e.g. lecithin or acacia), non-aqueous vehicles (which may include edible oils e.g. almond oil, oily esters, ethyl alcohol or fractionated vegetable oils), preservatives (e.g. methyl or propyl-p-hydroxybenzoates or sorbic acid), and, if desired, conventional flavourings or colorants, buffer salts and sweetening agents as appropriate.

Formulations for injection may be presented in unit dosage form e.g. in ampoules or in multi-dose, utilising a compound of the present invention or pharmaceutically acceptable salt thereof and a sterile vehicle, optionally with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilising and/or dispersing agents. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g. sterile pyrogen-free water, before use. The compound, depending on the vehicle and concentration used, can be either suspended or dissolved in the vehicle. In preparing solutions, the compound can be dissolved for injection and filter sterilised before filling into a suitable vial or ampoule and sealing. Advantageously, adjuvants such as a local anaesthetic, preservatives and buffering agents are dissolved in the vehicle. To enhance the stability, the composition can be frozen after filling into the vial and the water removed under vacuum. Parenteral suspensions are prepared in substantially the same manner, except that the compound is suspended in the vehicle instead of being dissolved, and sterilisation cannot be accomplished by filtration. The compound can be sterilised by exposure to ethylene oxide before suspension in a sterile vehicle. Advantageously, a surfactant or wetting agent is included in the composition to facilitate uniform distribution of the compound.

Lotions may be formulated with an aqueous or oily base and in general will also contain one or more emulsifying agents, stabilising agents, dispersing agents, suspending agents, thickening agents, or colouring agents.

Such long acting formulations may be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds of the present invention or pharmaceutically acceptable salts may be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.

For intranasal administration, the compounds the present invention or pharmaceutically acceptable salts thereof may be formulated as solutions for administration via a suitable metered or unitary dose device or alternatively as a powder mix with a suitable carrier for administration using a suitable delivery device.

The compounds of the present invention and pharmaceutically acceptable salts thereof may be formulated for topical administration in the form of ointments, creams, gels, lotions, pessaries, aerosols or drops (e.g. eye, ear or nose drops). Ointments and creams may for example, be formulated with an aqueous or oily base with the addition of suitable thickening and/or gelling agents. Ointments for administration to the eye may be manufactured in a sterile manner using sterilized components.

A P2X7 antagonist may be usefully combined with another pharmacologically active compound, or two or more other pharmacologically active compounds, particularly in the treatment of inflammatory, pain and urological diseases or disorders. For example, a P2X7 antagonist, particularly a compound of the present invention, or a pharmaceutically acceptable salt or solvate thereof, as defined above, may be administered simultaneously, sequentially or separately in combination with one or more agents.

Such combinations offer significant advantages, including synergistic activity, in therapy.

The composition may contain from 0.1% to 99% by weight, preferably from 10% to 60% by weight, of the active material, depending on the method of administration. The dose of the compound used in the treatment of the aforementioned disorders may vary in the usual way with the seriousness of the disorders, the weight of the sufferer, and other similar factors.

A therapeutically effective amount of a compound of the present invention or a pharmaceutical composition thereof includes a dose range from about 0.05 mg to about 3000 mg, in particular from about 1 mg to about 1000 mg or, more particularly, from about 10 mg to about 500 mg of active ingredient in a regimen of about once a day or more than once a day, for example two, three or four times a day for an average (70 kg) human; although, it is apparent to one skilled in the art that the therapeutically effective amount for active compounds of the invention may vary as well the diseases, syndromes, conditions, and disorders being treated.

For oral administration, a pharmaceutical composition is preferably provided in the form of tablets containing about 0.01, about 0.1, about 1, about 10, about 50, about 100, about 150, about 200, about 250, and about 500 milligrams of the inventive compound as the active ingredient.

Advantageously, a compound of the present invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three and four times daily.

Optimal dosages of a compound of the present invention to be administered may be readily determined and may vary with the particular compound used, the mode of administration, the strength of the preparation, and the advancement of the disease, syndrome, condition, or disorder. In addition, factors associated with the particular subject being treated, including subject age, weight, diet and time of administration, will result in the need to adjust the dose to achieve an appropriate therapeutic level.

The following Examples and Intermediates were prepared by General Procedure C, D, or E (Tables 17 and 19).

General Procedure C

O₃ was bubbled into a solution of substrate (1.0 eq.) in 50% CH₂Cl₂-MeOH at −78° C. until starting material consumed. N₂ were bubbled into the mixture to remove the excess of O₃ at −78° C. The mixture was quenched with NaBH₄ (10.0 eq.) and the mixture was warmed to room temperature gradually. After being stirred at room temperature for 1 h, 10% aq. citric acid was added to the mixture. The mixture extracted with CH₂Cl₂ 3 times and the extracts were washed with water. The extracts were combined, dried over Na₂SO₄, and concentrated in vacuo. The resulting residue was purified by NH gel column chromatography and/or SCX cartridge column, preparative HPLC to afford the following Examples and Intermediates.

General Procedure D

Sodium borohydride (1.5 eq.) was added to a solution of substrate (1.0 eq.) in MeOH and the mixture was stirred at room temperature until complete reaction. Water was added to the mixture and the volatile was removed by evaporation. The residue was extracted with EtOAc and washed with brine. The extract was dried over Na₂SO₄ and concentrated in vacuo. The resulting residue was purified by NH gel column chromatography and/or SCX cartridge column, preparative HPLC to afford the following Examples and Intermediates.

General Procedure E

To a solution of substrate in CH₂Cl₂ (0.065 M) was added TFA (0.065 M) at room temperature. The mixture was stirred at room temperature until complete reaction, the mixture was poured into water. The mixture was extracted with CH₂Cl₂. The extract was washed with water, dried over Na₂SO₄ and concentrated in vacuo to afford the following Examples and Intermediates.

The following Examples and Intermediates were prepared by General Procedure N (Tables 38 and 40).

General Procedure N

A mixture of substrate (1.0 eq.) and 2 N aq. NaOH (2.0 eq.) in MeOH was stirred at room temperature for 1.5 h, 2 N hydrochloric acid (2.2 eq.) was added to the mixture. The mixture was concentrated in vacuo. Toluene and MeCN was added to the resulting mixture and concentrated in vacuo. This procedure was repeated 3 times to remove remaining water. The residual powder was dissolved with THE and amine (1.1 eq.), triethylamine (1.3 eq.), and DMT-MM (1.8 eq.) were added to the mixture at ambient temperature. After being stirred until complete reaction, the insoluble material was removed by filtration, and the filtrate was concentrated in vacuo. The resulting residue was purified by silica gel column chromatography, and/or SCX cartridge column, and then preparative HPLC to afford the following Examples and Intermediates.

The following Intermediates were prepared by General Procedure AA (Table 56).

General Procedure AA

To a stirred solution of substrate (1.0 eq.), iodomethane (15 eq.), and silver(I)oxide (10 eq.) in THE was added one drop of dimethyl sulfide at ambient temperature in the dark. The mixture was stirred at room temperature for 1 h, and then heated to 50° C. After being stirred at 50° C. until complete reaction, the mixture was cooled to room temperature. The insoluble material was removed by filtration, the resulting filtrate was concentrated in vacuo. The residue was purified by silica gel column chromatography to afford following Intermediates.

Metabolic Stability Assay:

Human Liver Microsomal Clearance of Test Compounds.

The in vitro elimination half-life estimates (t_(1/2)) and in vitro intrinsic clearance values (hCL_(int,u)) were observed from metabolic stability in human liver microsomes.

Incubation with Liver Microsomes

Stock solutions of test compound were prepared at 10 mM (as active compound) in DMSO. The stock solution was diluted immediately before use to 50 microM using 50% acetonitrile-water mixture solution (v/v) to produce working solution. The NADPH-regenerating solution was prepared on the day of analysis by diluting 1 volume of 80 mM NADP⁺ (ORIENTAL YEAST) with 1 volume of 240 mM MgCl₂ (WAKO) and 1 volume of 320 mM of glucose-6-phosphate (Sigma-Aldrich) and 1 volume of 32 U/mL of glucose-6-phosphate dehydrogenase (Sigma-Aldrich) and 2 volume of 200 mM UDP-GA (Nacalai) and 2 volume of 6.6 mM beta-NAD (ORIENTAL YEAST), respectively. Immediately prior to use, the reaction mixture was produced mixing 1 volume of the NADPH-regenerating solution with 6.8 volume of 125 mM potassium phosphate assay buffer. Human liver microsomes (XenoTech, pooled, mixed-gender human microsomes) were diluted to 2.5 mg protein/mL using 125 mM potassium phosphate assay buffer. Two microliters of working solution of each test compound and 78 microL of reaction mixture were added to 96 well cluster tubes (Micronic) in duplicate.

The tubes were placed in an incubator at 37° C. for 5 minutes before adding the human liver microsomes. A 20 microL of aliquot of the human liver microsome solution (2.5 mg protein/mL) was added to each original well to initiate metabolism. Incubation was performed at 37° C. At 15 minutes, the plate was removed from the incubator and a solution containing internal standard (200 microL, 1 microM reserpine, 50 nM buspirone and 1 microM tolbutamide in 100% acetonitrile) was added to each well. The plate was then spun in a centrifuge at 3500 rpm for 15 minutes at 4° C. A supernatant was transferred from each well to a 96-well shallow plate and then diluted with 4 volume of the mobile phase (A).

LC-MS/MS Analysis

Quantitative analysis of test compound in quenched reaction mixture was performed using the LC-MS/MS system, which consisted of an Agilent 1100 series gradient HPLC pump (Agilent Technologies), a CTC HTS PAL Autosampler (AMR), and a Sciex API 3200 triple quadrupole mass spectrometer (Sciex) equipped with a turbo ionspray interface. The Chromatographic separation was achieved using reverse phase HPLC with an Inert Sustain RP C18 50×2.1 mm column (GL Science) or Capcell Pak RP C18 50×2.1 mm column (Shiseido). The column temperature was 40° C., and the flow rate was 0.4 mL/min. The mobile phase consisted of 2 solvents: (A) 0.1% formic acid in water and (B) acetonitrile or 0.1% formic acid in acetonitrile. The compounds were eluted with a step gradient achieving 5% to 90% of B in 0.7 min, 90% of B in 1.3 min and then returned to initial conditions for equilibration (1.5 or 1.6 min). The mass spectrometer was operated in multiple-reaction-monitoring mode. Integration of test compound and internal standard peak was performed using Analyst Software (version 1.6). The area ratio of each test compound was calculated by comparing the peak area of the compound to the peak area of an internal standard.

Calculation of Human Liver Microsomal Intrinsic Clearance (hCL_(int,u))

The mean peak area ratios were calculated by averaging the peak area ratios (n=2) of a compound and internal standard for each sample. Metabolic stability was determined by plotting the natural logarithm of the mean peak area ratio of unchanged test compound as a function of time. Percent remaining was calculated by determining the ratio of the mean peak area ratio at incubation time to the mean peak area ratio of the time-zero samples. The rate of loss of test compound was calculated using the equation k=[Ln(C₀)−Ln(C)]/incubation time, where C⁰ was the initial mean peak area ratio of the test compound, C was the mean peak area ratio of test compound remaining after incubation (C=C₀×remaining ratio), and the incubation time was 15 min. The t_(1/2) was estimated using the equation t/2=0.693/k. The hCL_(int,u) was estimated using the equation hCL_(int,u)=k/(microsomal protein concentration)×(microsomal protein per gram of liver)×(liver mass per kilogram of body mass)/(human microsomal fu), where the microsomal protein concentration was 0.5 mg/mL, and the physical and physiological scaling factors were used such as the microsomal protein per gram of liver (48.8 mg) and, the liver mass per kilogram of body mass (25.7 g), and the human microsomal fu was determined experimentally from the human liver microsomal binding assay.

The compounds of this invention show preferable stability, which show the above-mentioned practical use.

CYP inhibition assays (CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6 and 3A4) were performed with recombinant CYP enzyme (BD Gentest) and Promega assay kits (P450-Glo Assays) in 384 well plate (Corning). Each product's catalog number is shown in Table 68.

Stock solutions of test compound were prepared at 10 mM (as active compound) in DMSO. NADPH-regenerating solution for each well was prepared on the day of analysis by diluting 0.4 microL of NADPH-A reagent (BD Gentest), 0.08 microL of NADPH-B reagent (BD Gentest) and 3.52 microL of water, for CYP 1A2, 2B6, 2C8, 2C9, 2C19 and 2D6. For CYP3A4, 1.6 microL of 1 M KPO₄, 0.4 microL of NADPH-A reagent and 0.08 microL of NADPH-B reagent, and 1.92 microL of water was mixed for each well. CYP enzyme mixture was prepared by following mixing ratio: 0.96 microL of water, 0.8 microL of 1 M KPO₄, 0.16 microL of Luciferin-ME, CYP1A2 Enzyme 0.08 microL/well for CYP1A2, 1.176 microL of water, 0.8 microL of 1 M KPO₄, 0.008 microL of Luciferin-2B6, CYP2B6 Enzyme 0.016 microL/well for CYP2B6, 1.04 microL of water, 0.4 microL of 1 M KPO₄, 0.24 microL of Luciferin-ME, CYP2C8 Enzyme 0.32 microL/well for CYP2C8, 1.56 microL of water, 0.2 microL of 1 M KPO₄, 0.16 microL of Luciferin-H, CYP2C9 Enzyme 0.08 microL/well for CYP2C9, 1.552 microL of water, 0.4 microL of 1M KPO₄, 0.008 microL of Luciferin-H EGE, CYP2C19 Enzyme 0.04 microL/well for CYP2C19, 1.136 microL of water, 0.8 microL of 1 M KPO₄, 0.024 microL of Luciferin-ME EGE, CYP2D6 Enzyme 0.04 microL/well for CYP2D6, 1.916 microL of 100 mM Tris-HCl, 0.004 microL of Luciferin-PPXE, CYP3A4 Enzyme 0.08 microL/well for CYP3A4. Four microL of NADPH-regenerating solution was placed in 384 well plate, and then 2 microL of stock solution of test compounds and 2 microL of CYP enzyme mixture were added into each well. The plate was spun down and incubated at each condition as shown in Table 69. After incubation, 8 microL of Luciferin Detection Reagent for each CYP enzyme was added into each well and stirred by plate shaker (BioShake XP, WAKEN B TECH) at 1000 rpm for 1 min. The plate was incubated for 30 min at room temperature, protected from light. Luminescence was measured by luminometer (Ultra, Tecan and EnVision, PerkinElmer). Luminescence signals were used to determine percent inhibition at 10 microM of test compound. A separate control incubation for chemiluminescence contained test compound (10 microM) and control CYPs.
